Answer 1

With a loop:

Folder = 'C:\Your\Path';  % Adjust the path to your needs
List   = dir(fullfile(Folder, '*.mat'));
C      = cell(size(List));
for k = 1:numel(List)
  Data = load(fullfile(Folder, List(k).name));
  M    = Data.??? % Unfortunately you do not reveal what in the MAT files is.
  % Perhaps:
  % M = Data.Value;
  C{k} = imresize(M, [512, 512]);  % See KSSV's answer
end
Result = cat(3, C{:});
save('Output.mat', 'Result');
